1. The problem statement, all variables and given/known data Two point charges q1 = 8.10×10-5 C and q2 = 3.24×10-4 C are separated by a distance d = 0.10 m. Compute their net electric field E (x) as a function of x for the following positive and negative values of x, taking E to be positive when the vector E points to the right and negative when E points to the left. Diagram shows 2 charges q1 and q2 (q1 is on the origin, q2 is distance d to the right along the x axis. a)What is E(-0.100)? b)What is E(-0.050)? c)What is E(-0.010)? etc.... 2. Relevant equations E = kQ/r^2 3. The attempt at a solution no idea where to start this problem. I know how to calculate the electric field but I don't get what it means when it says "as a function of x" (what is x? there is no x on the diagram, just 2 point charges and the distance between them). If someone could walk me through a, I could do the rest! Thanks!
